Folger Deep Conductivity Temperature Depth Deployed 2024-10-07

Folger Deep is a deep location in Folger Passage near a pillar-like seamount, where productivity and marine mammals are observed. This device is a Conductivity Temperature Depth.

Conductivity Temperature Depth (CTD) is an instrument package that contains sensors for measuring the conductivity, temperature, and pressure of seawater. Salinity, sound velocity, depth and density are variables that can be derived from sensor measurements. CTDs can carry additional instruments and sensors such as oxygen sensors, turbidity sensors and fluorometers.
